Manchester United's Champions League Return: Defensive Concerns Loom

Manchester United’s long wait for Champions League football ends tonight – but an old problem threatens to overshadow their return.

Three years after their last appearance in the competition, United step back under the bright lights against Sabah FK. The scars of 2023 still linger: dumped out at the group stage, bottom of their pool, and with Erik ten Hag overseeing a dismal 2023/24 campaign that left the club out in the cold.

The landscape has changed since then. The Champions League format is new, the table now stretches to 36 teams, and the margin for embarrassment is different. If Michael Carrick’s side end up anywhere near the bottom this time, it will signal a crisis of a very familiar kind.

Defence under the microscope

Senne Lammens is set to start in goal, a straightforward decision in a team where very few feel nailed on. In front of him, the questions begin.

United’s back line has leaked too many chances, too often. It needs to tighten up quickly if this European campaign is to last beyond the bare minimum. Diogo Dalot is likely to keep his place at right-back, his attacking thrust still valued despite those defensive frailties.

At centre-back, change feels imminent. Leny Yoro is pushing to come in alongside Harry Maguire, with Lisandro Martinez looking short of rhythm and sharpness in recent outings. Resting Martinez now, with the Manchester derby looming at the weekend, would be as much about protection as punishment – a chance to take him out of the firing line and reset.

Then comes the real headache.

Left-back gamble comes home to roost

All eyes will be on the left side of that defence when the team sheet drops. United’s failure to properly reinforce at left-back over the summer is now being brutally exposed.

Luke Shaw did not train on Wednesday. Carrick insisted there were no injury concerns and that Shaw had simply been handed a rest day. Even so, with a tight turnaround before Sunday’s derby, that absence all but rules him out of starting tonight. United can’t afford to push him and lose him.

Harry Amass did train, but throwing the youngster into a Champions League opener would be a huge leap of faith. Patrick Dorgu offers another option, but his strengths lie higher up the pitch, where his energy and attacking instincts can do more damage.

So the solution is likely to be a compromise: Noussair Mazraoui shuffling across to left-back. It’s not ideal, and everyone at the club knows it. This is exactly the sort of scenario United risked when they chose not to properly address the position in the market. Now, on the eve of a European return and days before a derby, they are patching and reshuffling instead of rotating with confidence.

Midfield settled, attack managed

In midfield, at least, there is some clarity. Kobbie Mainoo will start, the young midfielder now central to how United build and control games. Youri Tielemans is expected to line up alongside him again, offering experience and passing range to complement Mainoo’s dynamism.

Ahead of them, there is no debate. Bruno Fernandes remains the first name on the teamsheet, the creative hub in the advanced role, and the player United will lean on when the tempo dips or the game threatens to drift.

Up front, the plan is more cautious. Benjamin Sesko’s minutes are being carefully managed, and with City on the horizon, it would be a major risk to start him tonight and effectively rule him out of beginning the derby. United cannot afford to burn him out before Sunday.

That opens the door for Matheus Cunha to lead the line, with Bryan Mbeumo and Marcus Rashford providing support from the flanks. It’s a front three with pace and movement, capable of stretching Sabah and creating the kind of chaos United have too often failed to exploit in Europe.

The stage is set: a new format, an old competition, and a club desperate to reassert itself. The question is whether this patched-up defence – and that fragile left flank – can hold long enough for United’s attacking talent to make this Champions League return feel like a new chapter, rather than a repeat of the same story.
